BarCamp is a informal meeting that don't have any subject.All attendee can speak anything without formality.Speaking only is Ok. A presentation is no problem.But, we have 20 minutes of speaking time include Q&A.

This Barcamp was held in Korea firstly. Some companies support this Barcamp include DAUM, OnNet and TatterTools,

I delighted to have an opportunity of attending the Barcamp because the number of attendee was limited to 50.

I made a presentation about the story of programmers. This story is based on my blog.

This BarCamp was very useful and so I would like to attend the next Barcamp.

North Korea carried out its first nuclear bomb test on Monday (Oct. 9).Actually, we had anticipated their first nuclear bomb test at the end of the year.But, they committed the test quickly.I think that it is a “flagrant and brazen” violation of international opinion.

Seoul has made every effort to maintain the peace of the Korean peninsula. Gaesong Industrial park and the Mt. Gumgang(Gumgansan) tour are good examples of the effort.

There was good chance for North Korea in terms of the six-way talks. But the US didn't think that North Korea is a partner. They imposed sactions on North Korea such as financial. So North Korea tried to test their missile in east sea. As a result, North Korea tested nuclear weapon.

Now the US has to change the altitude for North Korea. BecauseNorth Korea want to have diplomatic intercourse with the US.

I enjoying hiking a mountatin.There are so many mountains & national parks in Korea.I think that Mt.JiriSan is the most beautiful mountatin in Korea.I had hiked Mt.JiriSan serveral times.As you may know, there are many tops in Mt.JirisanYou can reach many tops when traverse the mountain ridge of Mt.Jirisan. And You can see beautiful sights from the tops like the above photo. This photo was taken at the top of CheonwangBong that is the most highest top in Mt. Jirisan.At that time, the season was winter and the weather was very clear as you can see. This was the first time to get the clear sky like this after I had hiked up the CheonwangBong.Anyway, I recommand that you will hike up Mt. Jirisan if you have free time.

Thanks.

This is the conference for celebrating 10th aniversity of KLDPKLDP is the acronym of Korea Linux Documentation Project, but now KLDP is a community group for free/open source softwares.

Actually, KLDP has started from a personal web site and now have become the representative community of Linux & free/open source software in terms of being helped by many deverlopers. As a result, We've got many outcomes such as linux documentation, open souce project hosting, community and blogs for developers.

The Web is an increasingly important resource in many aspects of life: education, employment, government, commerce, health care, recreation, and more.Howerver it is very dangerous if these resources only can be accessible for a specific web browser.

As you know, Most of people use Internet Explorer as web browser in Korea.Internet Explorer supports incompatible features such as ActiveX, Some of JavaScript.The problem is that Many web sites support the features include the government web sites in Korea.

Actually, Web accessibility means that people with disabilities can use the Web. But It is more dangerous that web sites can be accessible for the specific web browser.

Now, Many linux & Mac users can not use internet banking, shopping mall sites, steaming service. Because these features are only implemented using ActiveX technology.

Moreover, Many web sites still use table tag for making the frame of web site. Other web browser can not render the web pages like Internet Explorer. So instead of using table tag for framing web pages, we have to use CSS, XHTML for making web pages.

Fortunately, the market share of Firefox is increasing now. And many people realize the problem of web accessibility.

PlayStation3 will be released at the end of this year. It seems the last hope of SONY. As you know, SONY has a problem with the profit decline. Actually, SONY adhered to the Trinitron TV that was the most popular analogue TV in 90s. As a result, they were late to join the DTV market: SONY did not invest LCD panel or PDP and so they was not able to make better digital TVs than other competitors.

The PS3 will come in two configurations: one version with a 60GB hard drive that will cost $599, and the second with a 20GB hard drive that will come in at $499

The PS3, which is based on the Cell processor, will support Blu-ray media. It also includes built-in Bluetooth and Wi-Fi connectivity, as well as Ethernet. Further, it includes Dolby digital surround sound functionality and supports high-definition video up to 1080p.

The console also can run up to seven wireless controllers at once, and all PS3s will come with a built-in hard drive, either 60GB or 20GB.

It was long time than I expected and compared with Microsoft.As you know, Apple is a computer manufacturer, MS is a software company. Two companies have helped each other and have competitive relationship.Two companies are developing different operating system but MS is developing software for MAC.

It is interesting that the first version of MS Excel was for Mac and Internet Explorer was the official web browser of Mac before releasing Safari that is Apple's web browser.

But now, two companies compete more than before. Apple is also developing a office software and web browser

For latest 10 years, Apple had been at a crisis so Steve Jobs could return with his company NEXT and write successful stories with Mac OSX and iMac series.

It may be said that Apple is at the turning point in success of iPod and iTunes Music Store. As a result, Apple is not only a computer manufacturer but also a CE maker & contents provider.

Apple had released the 20th anniversary model of Mac, but there is no news about the 30th anniversary model. I am looking forward to new present from Apple.

I expect that Apple leads technology of computer & CE device areas by its bright ideas and makes computing environment be easier and comfortable.

Web 2.0 is so powerful to dominate our new life on the Internet. del.icio.us is the shared bookmark service that adopts the concept of web 2.0 and Flickr is also a good example of web 2.0.They are using the concept of tags. We can attach tag to pictures or bookmarks. Tag is like keyword that presents the meaning of something. Before, I only classify something to one category. Now, We can classify pictures or bookmarks to several category that using tags.It's so great!

At last, I bought a video iPod that is the 5th generation of the iPod family. It is thinner and lighter than I expected. Using an iPod is very easy for me because I already have used iTunes on my Mac. In addition, I have many mp3 files and video files in my iTunes music library. The problem is that I have to resize video files to move to iPod. Fortunately, iTunes can resize the video files, which have a large screen size, to play well on the iPod. Of course it takes a lot of time to covert the size of video. Anyway, It is good to enjoy the video on my new iPod when moving.

Today’s topic is about flash memory.Flash memory is one of memory you are using everyday in your mobile devices.Almost memories on your PC lose data when the power is off. However, flash memory can maintain data though the power is off. You are already experienced that your mp3 player never loses music files.

What is Flash Memory?Flash memory is non-volatile, which means that it does not need power to maintain the information stored in the chip. In addition, flash memory offers fast read access times (though not as fast as volatile DRAM memory used for main memory in PCs) and better shock resistance than hard disks. ( from wikipedia)

Therefore, there are many applications that use flash memory such as storage on battery-powered device like MP3 Player, mobile phone and PDA. In addition, External USB storage we are using has a flash memory.

Flash memory is made in two forms: NOR flash and NAND flash. The name refers to the type of logic gate used in each storage cell. Almost flash memory we are using to store data is NAND flash. NOR flash is used for running program like DRAM.

As you know, SAMSUNG is world's largest NAND flash memory chipmaker. The market share is 60%(?). The success of Apple's iPod enlarges the market of flash memory. So INTEL has a plan to produce NAND flash memory with Micronics that is one of the memory manufacturer in the US.

Followed by Hwang's law, Samsung under Hwang has redoubled chip capacity every year since 1999, creating an industrial pattern named "Hwang's law," overturning the previous "Moore's law" that had correctly observed the number of transistors per integrated circuit would double every couple of years.(from Korea times)

Anyway, more information will be stored to flash memory for future. Flash memory may replace hard disk.
